These plugs close the drain openings in the pump housing and ensure a watertight<br \/>\nseal during normal operation, while remaining easy to remove when it is time to drain the pump for winter or maintenance.<\/p>\n<h3>Main Features Of The Pentair Drain Plug Set R357161<\/h3>\n<ul>\n<li>Original Pentair drain plugs with integrated seals for Whisperflo and Superflo pumps.<\/li>\n<li>Supplied as a set of two plugs to equip both drain ports on the pump housing.<\/li>\n<li>Threaded design for secure tightening and easy removal by hand or with a suitable tool.<\/li>\n<li>Elastomer sealing ring on each plug for a reliable, leak free closure.<\/li>\n<\/ul>\n<h3>Function And Role In The Pump Housing<\/h3>\n<p>The drain plugs are fitted to the lowest points of the pump body so that water can be emptied completely before winter or whenever<br \/>\nmaintenance requires a dry housing. During the season, the plugs must seal perfectly to prevent drips and air entry on the suction side.<\/p>\n<ul>\n<li>Allow quick draining of the pump to protect against frost damage.<\/li>\n<li>Seal the drain openings during normal operation to keep the housing watertight.<\/li>\n<li>Help maintain stable priming by preventing air leaks around the base of the pump.<\/li>\n<\/ul>\n<h3>Compatibility And Typical Use<\/h3>\n<p>The Pentair Whisperflo and Superflo drain plug and seal set of 2 R357161 is designed for use on compatible Pentair pump housings<br \/>\nthat feature twin drain ports. It follows the original thread and seal dimensions, so it can be installed directly in place of<br \/>\nworn or missing plugs.<\/p>\n<ul>\n<li>Suitable for Pentair Whisperflo pumps that specify reference R357161 for drain plugs.<\/li>\n<li>Compatible with Pentair Superflo pumps using the same lower drain configuration.<\/li>\n<li>Ideal when refurbishing a pump housing or replacing plugs damaged by tools, frost or ageing.<\/li>\n<\/ul>\n<p>Always check the parts diagram for your exact pump model. If the drain plug kit is identified as R357161, this is the correct<br \/>\nreplacement set.<\/p>\n<h3>When To Replace The Drain Plugs And Seals<\/h3>\n<p>Although small, the drain plugs and their seals are critical for proper sealing and frost protection. Over time, plastics and<br \/>\nelastomers can harden, deform or crack under the effects of chemicals, UV and repeated handling.<\/p>\n<ul>\n<li>Persistent drips from one of the drain ports even after tightening the plug.<\/li>\n<li>O rings that appear flattened, cracked or are missing completely.<\/li>\n<li>Plug heads rounded off or damaged by pliers or unsuitable tools.<\/li>\n<li>Evidence of past frost damage or housing replacement where new plugs are recommended.<\/li>\n<\/ul>\n<h3>Installation And Handling Guidelines<\/h3>\n<p>Installing the Pentair drain plug and seal set of 2 R357161 is straightforward and can be carried out during normal maintenance<br \/>\nof the pump or when preparing the filtration system for winter.<\/p>\n<ul>\n<li>Switch off and isolate the pump before working on the housing.<\/li>\n<li>If removing old plugs, unscrew them carefully and allow any remaining water to drain fully.<\/li>\n<li>Clean the drain port threads and sealing surfaces to remove scale or debris.<\/li>\n<li>Check that the new plugs each have their sealing ring correctly seated in the groove.<\/li>\n<li>Screw the plugs into the drain ports by hand and tighten until snug; avoid over tightening.<\/li>\n<\/ul>\n<p>Before the start of the season, verify that both plugs are properly tightened and that no seepage appears around the drain area<br \/>\nwhen the pump is running.<\/p>\n<h3>Good Practice For Winterising And Maintenance<\/h3>\n<p>Using the correct original drain plugs and applying simple good practices helps protect the pump housing and extend its service life.<\/p>\n<ul>\n<li>In freezing climates, remove the drain plugs to empty the housing completely before winter.<\/li>\n<li>Store the plugs and seals in a safe place during the off season so they are not lost.<\/li>\n<li>Inspect the seals every season and replace the set at the first signs of ageing.<\/li>\n<li>Avoid using metal tools directly on the plug heads whenever possible to prevent damage.<\/li>\n<\/ul>\n<p>With a new Pentair Whisperflo and Superflo drain plug and seal set of 2 R357161 correctly installed, the pump housing remains<br \/>\nproperly sealed during normal use and can be drained quickly and safely whenever required.<\/p>","protected":false},"excerpt":{"rendered":"<p>Pentair Whisperflo And Superflo Drain Plug And Seal Set Of 2 R357161 The Pentair Whisperflo and Superflo drain plug and seal set of 2 R357161 is the original pair of winterising plugs with gaskets for the lower drain ports on Pentair Whisperflo and Superflo pool pumps.
